Abstract：Objective To explore the application value of low-dose multi-slice spiral CT in the diagnosis of elderly lung can-cer.Method 123 lung cancer patients were selected and divided into a low-dose group of 65 cases and a conventional dose group of 58 cases according to different scanning methods.The detection rate of lung cancer and scanning radiation parameters were compared between the two groups.Result There was no statistically significant difference in the detection rate of pulmo-nary nodules and early lung cancer between the low-dose group and the conventional dose group(P>0.05).There was no statisti-cally significant difference(P>0.05)between the low-dose group and the conventional dose group in terms of nodule diameter,follicular sign,lobulation sign,and calcification sign when examining pulmonary nodules.Compared with the conventional dose group,the low-dose group had lower ED values,DLP values,and CTDIvol values in radiation parameters,and the differences were statistically significant(P<0.05).Conclusion Low dose multi-slice spiral CT has a higher detection rate in diagnosing el-derly lung cancer compared to conventional dose multi-slice spiral CT.
